Sumo yechigadzirwa
Zita resainzi repropylene glycol ndi "1,2-propanediol". Racemate imvura ine hygroscopic viscous ine kuravira kunonaka zvishoma. Inosanganiswa mumvura, acetone, ethyl acetate uye chloroform, uye inonyungudika mu ether. Inonyungudika mumafuta akawanda anokosha, asi haisanganisike ne petroleum ether, paraffin ne grease. Inogadzikana zvakanyanya pakupisa nechiedza, uye inogadzikana zvakanyanya pakupisa kwakaderera. Propylene glycol inogona kuoxidized kuita propionaldehyde, lactic acid, pyruvic acid uye acetic acid pakupisa kwakakwira.
Propylene glycol idiol uye ine hunhu hwema alcohols akajairika. Inosangana nema organic acids nema inorganic acids kugadzira monoesters kana diesters. Inosangana ne propylene oxide kugadzira ether. Inosangana ne hydrogen halide kugadzira halohydrins. Inosangana ne acetaldehyde kugadzira methyldioxolane, mvura isina ruvara, ine viscous uye yakasimba inonwisa mvura, inenge isina kunaka uye isinganhuwi. Inosanganiswa nemvura, ethanol nezvimwe zvinonyungudutsa zve organic.
Munda wekushandisa
Inoshandiswa sezvinhu zvekugadzira maresini, mapurasitiki, masurfactants, maemulsifiers uye mademulsifiers, pamwe chete neantifreeze uye heat carriers

Ruzivo rweKambani
MIT-IVY INDUSTRY CO., LTD inogadzira uye inotumira kunze madhayi emakemikari akanaka uye mishonga yemishonga muChina.
Vanonyanya kugadzira zvigadzirwa zveaniline series uye zvigadzirwa zvechlorine series.
MIT –IVY Chemicals Industry Co.,Ltd. ikambani inotungamira mukugadzira makemikari kwemakore makumi maviri nerimwe ine michina yekugadzira yakakwana uye manejimendi nekuchengetedza michina zvine hungwaru.
Tinoshandisa tekinoroji yepamusoro yekugadzira uye nzira dzekuyedza kuti tiwane kugadzirwa, kudzora mhando kuti zvisvike padanho repamusoro. Takatenderwa neSGS, ISO9001, ISO140 01, GB/HS16949 uye T28001.
Zvigadzirwa zvikuru zveMit-Ivy zvinosanganisira zvinotevera:
API, mishonga yepakati, dhayi yepakati, makemikari akakosha, pendi yemumaindasitiri inoburitswa nemvura uye zvinhu zvitsva zvine simba.
Misika yedu mikuru inosanganisira America, India, Africa, Indonesia, Turkey, South-east Asia, West Asia nezvimwewo. MIT-IVY Industry Main products ine 97% yemusika wemuno unonyanya kugadzira nekutarisira, Tinogona kupa zvigadzirwa nemutengo unokwikwidzana. Nemhando yepamusoro uye mutengo uye tinokugamuchirai kuti mubvunze. Kambani yedu ine vanhu vane hunyanzvi vanodzidza nezve chemical R&D uye manejimendi, vanopa zvigadzirwa zvemakemikari zvakanaka zvine mhando yepamusoro uye sevhisi yepedyo, vanopawo zvigadzirwa zvakagadzirwa zvinoenderana nezvinodiwa nevatengi vedu. Tine timu yekutarisira yakanaka uye inozvikurudzira ine pfungwa yakafanana, ine hanya uye yakazvipira kuburikidza nekushanda pamwe chete, timu yedu inoedza kubudirira mukufadza vatengi vedu nesu. Tinogara tichigadzira zvigadzirwa zvedu uye tichivandudza network yedu yekutengesa. Saka, tinotanga nzira yekutanga yekutengesa pa internet muChina, inova kutengeserana kwezvitoro zvemapakeji madiki kuunza nzira dzakasiyana siyana dzekutarisira. Zvigadzirwa zvedu zvinotumirwa kune dzimwe nyika kuSouth Korea, Vietnam, Australia, Europe neSouth America, zvinokurudzirwa zvikuru nevatengi vedu. Tinosimbirira pakutenda kwemanejimendi "Musika ndiyo kambasi yedu, Hunhu hupenyu hwedu, Chikwereti mweya wedu". Kuvimba kwevatengi ndiko kwatinotungamira, kugutsikana kwavo ndicho chinangwa chedu chinotinetsa.
Basa reVatengi reBrand:
Chikwata chedu cheJIT customer service account muChina chinogadzira nekushandisa mazano akagadzirirwa vatengi vedu kuti vawane makemikari emumaindasitiri neakakosha zvakakwana.
Zvakanakira zvako:
● Kubatsira vatengi kwakabatana kunotsigira kurerutswa kwemaitiro ekutonga, zvichikonzera kuchengetedza nguva nemari.
● Network yedu yekuChina pamwe nemhinduro dzezvinhu zvine hunyanzvi zvinovimbisa kuti makemikari emhando yakafanana anopiwa kune vatengi vane nzvimbo dzakasiyana siyana dzekugadzira uye anobatsira mukuronga nekuvimbika kwemabasa.
● Maitiro edu anogara achigadziriswa uye achigadziriswa kuti aenderane nekuchinja kwemaumbirwo nezvinodiwa nevatengi vedu.
Kubudirira kwebasa reChemistry Logistics:
Basa rekugadzira zvinhu zvemakemikari nderehunyanzvi uye rinofanira kunge riri nani pasi peUN, kunyanya kune DGR Class series. Isu tinopa mhinduro yakakosha yekuvandudza basa rekugadzira zvinhu uye rakakodzera boka rekutakura zvinhu uye kunyora mazita kune vakuru vedu. Zviteshi zvedu zvikuru zveChinese zvine mawareji emakemikari eDGR ndezvekushandisa makemikari akakosha uye kushandisa mapepa ese ane chekuita nazvo.
Zvigaro zvedu zvekugovera zvinosanganisira:
● Kuendeswa kwezvinhu zvinochinjika, mhinduro dzakangwara
● Chero chinhu kubva pakutakura zvinhu zvakawanda zvezviuru zvematani kusvika pakutakura zvinhu zvidiki zvakapakwa uye kunyange masampuli.
● Huru - kuchengetwa nekutakurwa kwehupfu nezvinwiwa - kufamba kwezvinhu muzvikepe - hupfu nezvinwiwa zvakawanda
● Mishonga, nzvimbo yekuchengetera chikafu uye yekuchengetera chikafu zvinoenderana nezvinodiwa nemutemo
● Zvinhu zvakakamurwa zvichienderana nechikamu chebhizinesi uye kupatsanurwa kwenjodzi
● Kuchengetera nekutakura zvinodzorwa nekupisa
● Kudzora mitengo zvinobudirira
● Kurongedzazve, kuzadza madhiramu, kuisa mumabhegi, kubvarura uye kuisa matipi
